Is my Monaro going to fail the MOT?

Princey · 3 May 2012 at 14:11

My MOT is due in two weeks but I'm getting it done this Friday. The issue I have though is with my hazard lights. If I press the hazard button then the hazards will function correctly, flashing on and off. However when you turn them off the left side will often stay on constantly and you have to engage the hazards 2-3 times again to get it off. This does not affect turn signalling at all.

I suspect it would be a fail.

Have you tried swapping the relay? Might be easier than failing the MOT in the first place.

It's a new BCM to repair this, already been diagnosed. Garage can not order a single relay of this type unless ordered in bulk.

Sell them on as a job lot to Vauxhall?

Friken stupid cheap Vauxhall cars. :rolleyes:

Which bozo through it was a good idea to solder the relay on?

You need to find a friendly MOT tester and show him that they do turn off.

I use this garage, don't think they would be petty over that kind of thing.

Thanks, I'll have a play with my car tonight and see if I'd be willing to risk it and I'll consider that garage.

Virtually all modern cars use a body electronics controller which will have PCB mounted relays. Failure of these relays is far from a Vauxhall specific problem.

Indeed, it's what was wrong with my VTS in the end.

Torch [P4] · 3 May 2012 at 16:32

do you have a part number for the relay ?
i work in electronics manufacture and may be able to source one for you, soldering something as large as a relay should be very easy even for a novice

Princey · 3 May 2012 at 17:44

Thanks, I'll see if I can obtain that.

panthro · 3 May 2012 at 17:47

How much does it cost to repair it properly?

realscot · 3 May 2012 at 17:50

I love that something that is virtually never used outside of MOT time is so prone to failure.

I'd have thought people use the 'park anywhere' lights quite a lot and not just at MOT time?

Princey · 3 May 2012 at 18:41

The only time I've used them and the only time I realised they were broke was when I put them on to say thank you to a truck who moved over on the motorway.

[TW]Fox · 3 May 2012 at 18:49

Can you not get one from a breakers? Surely its shared with other cars on the same platform - the Monaro is a Commodore Coupe and the Commodore and the Omega were fundamentally the same car, plenty of Omegas about?

Princey · 3 May 2012 at 18:54

Nope, the BCM isn't a shared part with the Omega. It also has to be reprogramme when fitted.

Lopéz · 3 May 2012 at 18:59

If it displays this erratic behaviour during the test then yes, it will fail.

Pop the top off the relay and have a gander inside at what's going on, it could be as simple as a dirty contact or a dry joint.
